Moving mirrored object problem
uncheck orignis here -&gt; than it works as expected again.

i am pretty sure you did what i did too often when i was bloody beginner: you searched for a shortcut and just typed it in - until you found it. Problem is: nearly every key combination does something in Blender. So i just can recommend: do only use shortcuts if you are sure you know them. So you will avoid a lot of trouble - which i had ;)
